INSTRUCTIONS
Triac Controller for Proportional Control of
Electric Heating and Cooling
Pulser HC-LON
controls the temperature in a room control-
ling heating and cooling in sequence. The controller can
work either with internal sensor, external values taken from
sensors in the room or values taken from a Local Operating
Network (LON). There is a built-in potentiometer for setpoint
displacement. The controller works proportionally - the ratio
between on-time and off-time is varied to suit the prevailing
heat demand.
Mounting
Remove the front, the screw is located behind the set-point
knob. Mount the device vertically with the cooling flange
at the top. Use screws with a maximum head diameter of
5.5mm.
If
Pulser HC-LON
is to be used with the internal sensor, it
should be mounted about 1.5m above the floor at a location
with representative temperature for the room. It is essential
that air can flow around the device without hinderance from
furniture or doors.
Pulser HC-LON
emits about 10W which must be dissipa-
ted. Maximum ambient temperature at full load is +30°C.
Ambient temperature: 0 to +30°C non-condensing.
Protection class: IP20.
Electrical Installation
The installation has to be carried out by a qualified profes
-
sional and in accordance with applicable directives.
The supply voltage must be wired via a fully isolating
switch with a contact gap of at least 3 mm,
Supply voltage: 200...250 V AC, 50...60 Hz connects to
terminal block J3, terminals 13 and 14 (fig 1).
The load is connected between terminals 15 and 16 in
terminal block J3 according to fig 1.
Maximum load:
2300 W at 230 V AC, 10 A.
Minimum load:
230 W at 230 V AC, 1 A.
The cooling flange is live!
Terminal block J1 which is for voltages of 24 V AC and
sensors is presented later in this document.
Control Principle
Pulser HC-LON
pulses the full load. It adjusts the mean
power output to the prevailing power demand by propor-
tionally adjusting the ratio between on-time and off-time.
The pulse period (sum of on- and off-time) is constant
60s.
To eliminate radio frequency interference the device has
zero phase-angle firing.
There are four ways of configuring the output from
Pulser
HC-LON.
1:
230 V AC heating (fig 1).
Heating by triac control but no cooling
2:
230 V AC heating (fig 1).
24 V AC 3-point (increase/decrease) cooling (fig 5).
Heating by triac control and cooling by a valve with
3-point control.
3:
230 V AC heating (fig 1).
24 V AC thermo cooling (fig 6).
Heating by triac control and cooling by a valve with
thermal actuator 24 V AC.
4:
24 V AC thermo heating (fig 7).
24 V AC thermo cooling (fig 7).
Both heating and cooling by one 24 V AC thermal
actuator output each.
